Likarolo tsa Ceramic tsa Alumina bakeng sa Mekhoa ea ho Fefola ha E-Gun
St.Cera e hlahisa likarolo tsa letsopa tsa alumina tse hloekileng haholo tsa 99.8% tse etselitsoeng ka ho khetheha litsamaiso tsa mouoane tsa electron beam (E-gun). Likarolo tsena li kenyelletsa li-liner tse ka sebelisoang ho tjhesa, lithebe tsa ho thibela mahlasedi, li-insulator le lisebelisoa tsa ho kenya. Thepa ena e fana ka matla a phahameng a dielectric (15×10⁶ V/m), botsitso ba mocheso ho fihlela ho 1600°C, le ho hanyetsa hantle ho ts'oha ha mocheso le tlhaselo ea lik'hemik'hale ho tsoa linthong tse mouoane. Bokhoni ba rona ba ho sebetsa ka nepo bo fihlella li-geometri tse rarahaneng ka boholo ba bonyane ba likarolo tse 0.2mm, ho ba sephara 0.003mm, le qetello ea bokaholimo Ra0.1. Karolo ka 'ngoe e hlahlojoa ka 100% CMM bakeng sa ho nepahala ha litekanyo.

Likopo:
- · Likepe tse hulang ka sethunya sa elektroniki le likepe tsa mouoane
- · Lithebe tsa ho khelosa mahlakore le lipoleiti tsa ho bula
- · Li-insulator tsa motlakase le lisebelisoa tsa ho fepa
- · Lisebelisoa tsa ho kenya bakeng sa mehloli ea mouoane
Tlhahiso e nepahetseng ea Tlhahiso:
Ho otloloha: 0.005mm, ho otloloha: 0.005mm, ho chitja: 0.002mm, ho tsepamisa maikutlo: 0.01mm.
Melemo:
- · Ha ho na tšilafalo ea lifilimi tse tšesaane tse tsoang linthong tse ka sebelisoang ho bolaea libomo
- · E mamella maemo a phahameng a mocheso nakong ea mouoane
- · Bophelo bo bolelele ba tšebeletso – 5× e telele ho feta mekhoa e meng ea graphite
Ho iketsetsa:
Libopeho tsa sekoti tse ka sebelisoang ka ho khetheha, li-flange tse kenngoang, lipaterone tsa masoba, le liphetho tsa bokaholimo lia fumaneha.
